Quick question - How do you know when your PCIII is going bad? Mine "lost" my custom map one weekend and made the bike run like crap in the mid-range. I've had it installed for 8 months with no problems until now. Dyno Jet told me to clear the map and run it from stock to see if that works. If the bike runs fine, try a stock map and go from there. Im wondering if it is even worth the trouble to reinstall it and go through that headache instead of just sending it back and getting a new one.

while they do go bad from time to time it is fairly rare. i would follow their advise and they will tell you when to send it back. who did your custom map for you? they should have kept it on file or given you a copy of it on disk, if so about 5 minutes to re-load it back to the p/c. if not then you will prolly have to pay to have it done again and this time ask for a copy.

Dan Kyle did the map for me and I have a copy saved on my laptop. I removed the PC Friday morning because I was running late for work. What I don't want to do is reinstall it just to take it back out again, ship it back, and put in another one. I was thinking that if it happened once, chances are it will happen again so I just should get a new one. Thanks for the help.

I'm gonna go out on a limb and guess that the ground connection is bad or that you've recently installed something that puts ripple on the +12V supply on the bike. Or the rectifier in your alternator died.

In any case, this sounds like a power problem to me, but it's just a hunch.

Ok guys, I screwed up. It was my fault. It didnít hit me until I was putting everything back together last night. I have a disc lock that I keep in the trunk with the PC and Iím guessing that while I was out on some curves, the lock must have hit a few of the buttons on front the PC for the manual adjustments. This is possible since I donít have both the power commander and the lock secured in the trunk and both will tend to roll around back there if I get aggressive on the turns. I zip tied the PC to the inner frame with the buttons facing inside and the back exposed and I am going to figure out a way to tie that lock down so it doesnít move too so hopefully, this does not happen again.
